Application August 23, 1946, Serial No. 692,598

1 Claim.

My present invention relates to an improved lamp and more particularly to an illuminating means especially designed for use in lighting such devices as door locks on dwellings or other building structures.

The advantages of such a lamp are apparent in view of the difficulty encountered in locating the escutcheon plate and key opening of a door lock in the dark.

In the accompany drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claim.

In the drawings:

Figure 1 is a front elevational view of the lamp and base of my invention with the cover removed.

. Figure 2 is a vertical transverse sectional view.

Figure 3 is a perspective view of the upper contact; and

Figure 4 is a perspective view of the lower contact.

In the preferred embodiment of my invention herein illustrated, I utilize with the door frame 2, a block body 4 of suitable material as wood formed with a circular recess 6 in the upper portion thereof.

In this recess I employ a contact 8 of conducting spring metal formed with an offset arm l having holes [2 therein. A flange [4 also extending from the central circular portion 8 is inturned at [6, and the arm II] is secured to the block 4 by screws l8.

A spring connector bar 20 is secured to the block by screw 22 and extends vertically of the block, the offset 23 being in position to engage the flange l4 of the contact 8, and a lower offset 24 is positioned in a recess 26 of the block.

The contact 28 also of conductive spring metal is formed with a securing flange 30 having holes 32 through which the screws 33 secure the arm to the block 4, and a resilient ring 34 is fashioned at the free end of the arm contact 28 to receive and retain a lamp bulb 3B.

A cover 38 of suitable material having a rim 40 is secured on the block 4 by screws 4| and this cover gives a finished ornamental appearance to the device of my invention.

A push button 42 extending through an aperture in the cover 38 is secured by disk 44 to the ofiset 48 of the bar 46 lying against the bar 20 throughout most of its length. The wires 50 and 52 from the respective contacts 8 and 28 provide an electrical circuit from the battery B.

Thus with the light structure of my invention positioned above the door lock or the escutcheon plate, when the push button is pressed electrical contact is made between the bar 20 and the flange l4, the lower end of the bar 20 engaging the end contact of the bulb and the contact 34 engaging the periphery of the bulb base. The hood 54 will direct the rays of the lamp downward toward the lock and the lock will therefore be easily and readily visible for the insertion of the key.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

A door-lock illuminating device construction comprising a block approximately flat in general configuration and having a back face shaped to lie fiat against a supporting surface, the block overlying said surface and having a plurality of screw-receiving openings, spaced contacts recessed in the front face of the block and having screw-receiving openings, one of the contacts being integrally formed with a, bulb-receiving ring, an electric light bulb mounted in the ring, a spring-metal connecting bar recessed in said front face and having intermediate its ends a screw-receiving opening, one end portion of the bar being in permanent engagement with the bulb-supporting contact, the other end portion of the bar overlying and being normally spaced from the other contact, a cover fitted over the block and overlying the front face thereof and having a hood for the bulb, said cover overlying and constituting a stop limiting outward movement of said second-named end portion of the connecting bar, a push button protruding through the cover and secured to said second-named end portion and depressible to move the connecting bar inwardly into engagement with said secondnamed contact, and screws extending through all said screw-receiving openings and respectively connecting the block to said supporting surface and the contacts and connecting bar to the block, said screws being fully exposed and accessible upon removal of the cover, and the screws extending through the contacts respectively comprising lead-engaging terminals.
